Keys to Diagnosing Common Nutrient Deficiencies in Rice

Potash Deficient Rice

Described below are the most common nutrient related issues that occur in Mississippi rice production and a few distinctive characteristics to key on when trying to properly identify each issue in the field.  Nutrient issues in rice can take on many appearances, but coupled with field histories some of the keys below will aid in identification.  . . . → Read More: Keys to Diagnosing Common Nutrient Deficiencies in Rice

Rice Stink Bugs in Mississippi Rice

As more and more of the rice crop starts to head, it is time to start thinking about rice stink bug. We have been sweeping some grass around the Delta for the last few weeks, and the one general comment I will make is that populations have been fairly low in most areas. We have seen fairly high numbers in a couple places, but it was small patches of heading grass in isolated locations. . . . → Read More: Rice Stink Bugs in Mississippi Rice

How Can I Estimate Corn Yield?

Dent_Stage_Ear

Would you like to estimate your corn yield prior to the combine heading to the field? If you are willing to put in a little time, you can develop a reasonable yield estimate by following these guidelines. . . . → Read More: How Can I Estimate Corn Yield?

Rice Leaf Blast Confirmed in Mississippi

Typical symptomology of rice leaf blast

Typical symptomology of rice leaf blast

Last week’s weather pattern in the Delta provided near perfect conditions for rice blast (Pyricularia grisea) to occur.  Rice blast is generally categorized by the plant part infected (e.g., leaf, neck, panicle).  Blast favors mild humid weather, frequent rainfall, and extended periods of leaf wetness.  On susceptible cultivars, yield loss . . . → Read More: Rice Leaf Blast Confirmed in Mississippi

Checking peanuts? Take your shovel! Unlikely southern blight* expression found in south Delta.

Yesterday we found our first southern blight* damage to peanuts for 2014. The timing is not unusual, we generally start finding the disease when the crop canopy closes. What is unusual is where on the plants the disease was found.

Jason and I were in a large field of peanuts between Tchula and Greenwood. An occasional plant . . . → Read More: Checking peanuts? Take your shovel! Unlikely southern blight* expression found in south Delta.

“It ain’t over till it’s over!” / Turnrow Talks

“It ain’t over till it’s over!” Amazing as it seems, several producers have not laid poly pipe. After the five plus inches of rainfall we received last week, some producers are questioning the need to lay pipe this late in the season. With harvest for corn and rice  within 30 days, does it make sense to . . . → Read More: “It ain’t over till it’s over!” / Turnrow Talks

Foliar Soybean Disease Update: July 20, 2014

Target spot of soybean.  Note the yellow halo around lesions typified by concentric rings.

Foliar diseases of soybean continue to be observed throughout the state. At present, no soybean rust has been detected in Mississippi. However, aerial web blight, downy mildew, frogeye leaf spot, and target spot have all been observed in light to severe situations depending on field location. . . . → Read More: Foliar Soybean Disease Update: July 20, 2014

Vulnerability of Corn to Late-Season Issues?

Southern rust

Corn is not immune to yield loss until physiological maturity occurs. However, it is not nearly as vulnerable during late reproductive stages. This article includes a chart which should substantially help assess the risk of potential corn yield reduction during late reproductive stages. . . . → Read More: Vulnerability of Corn to Late-Season Issues?

Why did the Kernels near the Ear Tip not Fill?

Kernel Abortion

Incomplete kernel set is something you can’t ignore. These kernels often don’t fill because the plant can’t supply enough energy to support them. Therefore, if we want to improve our yields, we need to investigate reasons why the kernel set is less than desired, so we can improve in the future. . . . → Read More: Why did the Kernels near the Ear Tip not Fill?
